Operating Instructions
1. Connect inlet filter to FSC gun inlet.
2. Connect to Pressure Washer.
3. Turn water on and open valve. Open trigger gun for flow of water through nozzles. Nozzles
must have flowing spray. If not, remove tips and clean; reassemble, making sure that groove of
nozzle is parallel to spray bar. Use thread sealant when installing nozzles.
4. Start Pressure Washer. The Hammerhead is ready for operation.
5. Walk slowly behind the Hammerhead cleaning as you go. If striping occurs, slow down your
pace.
6. Periodically check weep hole on bottom of swivel. Water will seep slowly; if water shoots out,
stop and replace seals. Swivel assembly can be rebuilt.
7. For maximum effectiveness keep spray tips clean. If the machine vibrates, stop and clean spray
tips.
8. Grease the swivel with one or two grease gun pumps every 200 hours (or once about every 30
days of use).
